GREENHOUSE HEATING APPARATUS Russian patent published in 2002 - IPC

FIELD: heat engineering. SUBSTANCE: apparatus has boiler 2, heating system connected to boiler, condensate surface recovery unit 3 mounted in main gas conduit and adapted for heat recovery of boiler waste combustion products. Recovery unit is connected through water pipe to subsurface heating system 4. Apparatus is further equipped with combustion product condensate collector 5 provided with hydraulic gate 6, separator-drop catcher 7, channel 11 for discharging combustion products into atmosphere, gas distribution system with carbon dioxide generator 13, mixing chamber 14 and gas burner 15. Such construction allows waste combustion products to be heated in mixing chamber through mixing thereof with glowing combustion products and directing the entire flow of waste combustion products into heat recovery unit. EFFECT: improved economy by increased heating efficiency of heat recovery unit. 1 dwg
